Travelling to the US?

I have given this advice to a number of clients who were heading for the United States, for both business and pleasure – do not carry any confidential data on your devices, laptops, phones, USB drives etc, as US Border Security can copy those devices without a warrant. If you need access to such files whilst away – put them in your favourite cloud storage and download them once you get there.

Now the chances of Border Security wanting to copy your files are small, but if the files are that confidential do not carry them – cloud them.

Now it appears any data copied is stored in a database that has very few restrictions on who can search it:
